As for ChainLink, it's once again very likely going to be one of the hundreds and hundreds of shitcoins out there that are only here for a certain amount of time for the "founders" to make money off the project. It's freakin 2020 and for some reason some people still don't realize this. Remember OysterPearl? WaltonChain? Request Network? Nimiq? Polymath? Verge? Dragonchain? Crap, I could go on and on and on.
Personally, I think that LINK has nothing to do with those projects you mentioned. It is the first decentralized oracle. It
may succeed.
Ethereum or any other smartcontract blockchain platform will need an oracle. I don't know if it will be chainlink or any other project, but some oracle must exist. Otherwise, there is no reason for ethereum or ethereum-like platforms to exist.
Imo, we will have an oracle in top 5. It may not be chainlink.
If there is no oracle (or nothing that do what an oracle does), no ethereum.
.. then it dumps a billion in a minute.

Tesla volatility is much higher than that. Is tesla a shit company as well?
Volatility is very common in new technologies. Nobody knows how much is chainlink or tesla are worth. How will they perform in the near or distant future.
TEsla dumping 55 billion in a day.
